Ideal for BER testing and characterization of EDFAs, the IQS-3150 Variable Attenuator is designed for 24/7 production. Combining innovative design techniques, high-quality components and meticulous calibration procedure, it offers a fast settling time, for optimized efficiency.
Automatic Power Monitoring Option
The power monitoring option allows the attenuator output power level to be set directly. When enabled, this function ensures power stability, even if the source power fluctuates. This option also simplifies test setups, eliminating the need for an external power meter.
Rugged and Reliable
Flexible, fully programmable and built both for singlemode and multimode applications, the IQS-3150 features an extremely rugged design that only uses two moving parts—a rotating motor for the shutter and a linear motor for the filter—and state-of-the-art electronics. The attenuator’s optomechanical assembly was tested at its highest operating temperature, at a very high relative humidity level, and with a continuous incident optical power of 23 dBm at 1550 nm—the equivalent of eight years of operation in typical BER testing conditions. Results showed that the IQS-3150 can endure 24/7 operation for years without requiring maintenance.
Attenuation Modes
Choose from three attenuation modes: absolute, relative and X+B (complete user calibration offset features). Cycle through a repeatable sequence of customized attenuation steps. These modes apply to both singlemode and multimode fiber applications. What’s more, the IQS-3150 offers a user-friendly Windows environment, making for a first-class variable attenuator.
Applications
- BER testing
- EDFA characterization
- System/component loss simulation
- Accurate power-level monitoring
- Instrument calibration
- Linearity measurement
- High-precision variable optical source output
- Optical margin analysis
Featuring integrated power monitoring, the IQS-3150-BI allows you to precisely control the amount of power your receiver (Rx) under test detects and, therefore, to achieve proper BER measurements. The IQS-3150-CI or IQS-3150-DI enable similar characterization for multimode applications. When calibrating your system, you can choose from two offsets. The first one is wavelength-independent and can be used to account for loss in the test setup, if applied to the attenuation or power setting. The second offset acts as a calibration factor, ensuring wavelength-specific correction levels and compensating for loss due to patchcords and connectors.

Fully Compatible
The IQS-3150 is fully compatible with previous versions of the module, namely the IQS-3100B, BW, C and D models, providing for true plug-and-play upgrades of your previously owned 3100 series variable attenuators. While previous 3100 series models featured a monitor port, the IQS-3150 now comes with an integrated power monitor, avoiding the need for an external device.
